minmax: reduce min/max macro expansion in atomisp driver

2024-09-11T18:07:47Z

Avoid unnecessary nested min()/max() which results in egregious macro expansion. Use clamp_t() as this introduces the least possible expansion, and turn the {s,u}DIGIT_FITTING() macros into inline functions to avoid the nested expansion. This resolves an issue with slackware 15.0 32-bit compilation as reported by Richard Narron. Presumably the min/max fixups would be difficult to backport, this patch should be easier and fix's Richard's problem in 5.15.

Using clamp() instead of min_t(max_t()) is easier to read. It also reduces the size of the preprocessed files by ~ 193 ko.

media: atomisp: Fix eed1_8 code assigning signed values to an unsigned variable

ia_css_eed1_8_vmem_encode() is assigning values with a range of -8192 - 8191 to e_dew_enh_y and e_dew_enh_a both of which are of the VMEM_ARRAY type which maps to u16.

media: atomisp: set lock before calling vb2_queue_init()

2024-09-06T09:56:54Z

The vb2_queue_init() will expect the vb2_queue lock pointer to be set in the future. So for those drivers that set the lock later, move it up to before the vb2_queue_init() call.

media: atomisp: Improve binary finding debug logging

2024-09-06T09:56:54Z

The atomisp firmware contains a number of different pipeline binaries inside its firmware file and the driver selects the right one depending on the selected pipeline configuration. Sometimes (e.g. when the selected output resolution is too big) it fails to find a binary. This happens especially when adding support for new sensors. Improve the logging when this happens to make debugging easier: 1. Replace ia_css_debug_dtrace(IA_CSS_DEBUG_TRACE, ...) with standard dev_dbg() calls so that the logs can be enabled with dyndbg 2. Do not dump_stack() when this fails, doing so adds no useful extra info 3. With the dump_stack() call gone, remove the wrapper and rename __ia_css_binary_find() to ia_css_binary_find() 4. On error use dev_err() instead of dev_dbg() so that when things fail it is clear why they fail without needing to enable dyndbg Signed-off-by: Hans de Goede Link: https://lore.kernel.org/r/20240902095229.59059-3-hdegoede@redhat.com Signed-off-by: Mauro Carvalho Chehab
